Javascript – How to convert Date object without hours stamp to desired hours stamp

I want to convert the "from" date object starting from 00:00:01 and "to" date object ending with 23:59:59. How do i do that. Here’s my code.

let from = new Date(req.params.from);
let to = new Date(req.params.to);
console.log('from: ',from,'to: ',to)

result of console:

from:  2024-01-25T00:00:00.000Z to:  2024-01-25T00:00:00.000Z

I tried this method:

from.setHours(0,0,0,1);
to.setHours(23,59,59,999)

its result was:

2024-01-24T18:30:00.001Z 2024-01-25T18:29:59.999Z

Here hour stamp starts with 18 and ends in 06

    Here is a possible solution.
    I do not know if you are aware of how setHours works.

    Here is a simple description:
    When you create a Date object using a string like ‘2024-01-25T00:00:00.000Z’, it is automatically interpreted as being in UTC (Coordinated Universal Time). However, when you use the setHours method, it adjusts the time based on your local time zone.

    This is how you would achieve this.

    let from = new Date('2024-01-25T00:00:00.000Z');
let to = new Date('2024-01-25T00:00:00.000Z');
from.setUTCHours(0, 0, 1, 0);
to.setUTCHours(23, 59, 59, 999);
console.log(from.toISOString());
console.log(to.toISOString());

    and the output is:

    2024-01-25T00:00:01.000Z
2024-01-25T23:59:59.999Z

    I tried to run this code:

      let from = new Date();
  let to = new Date();
  console.log('from: ',from,'to: ',to);
  from.setHours(0,0,1,0);
  to.setHours(23,59,59,999);
  console.log('from: ',from,'to: ',to);

    and i got this output

    from:  2024-01-25T10:47:36.870Z to:  2024-01-25T10:47:36.870Z
from:  2024-01-25T00:00:01.000Z to:  2024-01-25T23:59:59.999Z

    Which looks to me like what you expected.
